Abstract
A tripod type constant-velocity joint includes an outer ring formed with three axially extending track grooves circumferentially spaced apart from each other by 120 degrees. Each track groove has a pair of opposed, axially extending side faces. A tripod member is inserted in the outer ring. The tripod member includes three protrusions each slidably received in one of the track grooves and having a pair of circumferentially curved side faces each opposing one of the pair of side faces of each track groove. Torque is thus transmitted between the outer ring and the tripod member. At least the protrusions of the tripod member are formed of a synthetic resin.
